Summary
@hotcappuccino/nodepull@1.0.0 ships a single index.js (the package's declared main ) that is wrapped in an obfuscator.io string-array + RC4-encrypted-string scheme. At top level — fires on every require('@hotcappuccino/nodepull') — the module loads child_process , fs , os , path , and an HTTP client; reconstructs a dotted URL through repeated ''.repeat(N,'.') concatenations of RC4-decrypted fragments; performs httpClient.get(URL + path) ; writes the response body to path.join(os.tmpdir(), <filename>) via fs.writeFileSync(..., {flag:'w+'}) ; and immediately invokes child_process.spawn(filePath, args, {windowsHide: true, cwd: os.tmpdir()}) . The 249-entry rotated string array is decoded by b / c using base64 + RC4 keyed by index 0, hiding the URL, spawned command, and required module names from inspection. There is no legitimate purpose served by RC4-encrypting every string (including module names) in a package whose only behavior is to fetch and execute a remote binary at import time. Any installer that requires this package executes attacker-controlled bytes from a hidden remote endpoint as a child process with the console window suppressed.
